Patent DE-19843728-A1 (DE)
Inventor: BEGEMANN ULRICH
IPC: D21F1/02
Filed: 1998-09-24
Abstract: To maintain the purity or to clean the low consistency flow at a stock inlet, at a machine for the production of paper or cardboard, the low consistency flow is given an increased proportion of solid particles. As the ratio of solid particles is increased in the low consistency flow, the solid content of the high consistency flow is reduced, where the sum total of the increased solids in the low consistency flow equals the solid reduction in the high consistency flow. The mass of increased solids at a section in the low consistency flow matches the mass of reduced solids in this section of the high consistency flow. The shifts in the amounts of solids between the high and low consistency flows are varied by volume control between the two flows, and between the same section in the two flows. The solid particles are fibers, and preferably long fibers of wood or plastics, with a high cleaning action. The solids are added to the low consistency flow continuously or at intervals. An Independent claim is included for a stock inlet with a pulp density control in sections across the machine width, with a high consistency (1) and a low consistency (2) flow. At least one feed (3) opens into the low consistency flow (2) to deliver solid particles into the flow of suspension. Preferred Features: The low consistency flow (2) has a number of feeds in sections where each of the feeds (3.1) delivers solid particles. A feed system delivers solid particles to sections of the high consistency flow (1). Each feed (3,3.1) for the solid particles has a control valve (7) to set the volume of delivered solids.

Abstract: The method involves altering the structure of the air flow channel. The air flow is generated by an impeller (3) of a fan (1) in a spiral channel of the fan casing and then conducted in a perpendicular deflector into a burner casing (8) at the side, to flow through air holes into a distributor element (13) in the burning zone of the fan burner.

A first stage of the reduction at the deflector is a linear baffle (14), preferably in the form of a lamella grating. An optional second stage of the reduction is a tube baffle (22), preferably in the form of an open cylinder grating (23) open at the end to the distributor element. An optional third stage of the reduction is a circular baffle in the form a grating with small holes, which homogenises the air flow in front of the distributor element.
